PROCESS Fon MAKINGBELTING.

To all whom t may concern:

Be it known that I, EDWARD F. GINGRAS, of the city of Buffalo, in the county 'of Erie and State of New York, have invented certain new and useful Improvements in Proc-k esses for Making Belting; and I do hereby declare the following to be a full, clear, and exact ,description of my invention, such as will enable others skilled in the art to which it appertains to make 4and use the same,i

reference being had to the accompanying drawings, and to lfigures of references marked thereon, which form part of specification. v

making belting, such 'as are disclosed in my application'filed on or about February 9, 1917, Serial Number 147,608, and renewed as Serial, Number 358,131, filed February 12, 1920, of which application" the present application is a continuation in part. The process constituting thisfinvention is particularly applicable tofabric belting for transmission of power, with or without an added coating of leather or the like for a frictional surface, using the yfabric for formV and strength. i

O ne ofthe objections by the, trade to the use of some forms of fabric belting, is theI lfailure of such` belts to maintain their form after a little use, especially when such belts become longer on one edge `than' theother, causing the belt to run to one side of the pulley. Wide a ged pulleys and guides have therefore bee resorted to for keeping the belt from running oj' the pulleys, and

this results in a quick abrasive destructing. i This destruction soon extends into thel body of the belt, owing l of theedges of the belt.

to additional strains accumulating from the loss of strength in the edges, much dis- `qualifying the belt for transmission service.

Therefore, one of thel objects of my invention is to provide such a process for 4treating fabric belts for use, whether for sei-vice with or without a` frictioning surface, as will havean operation included therein whicliwill bring about the treatment of the entire belt under a like condition throughout its length at one time, to bring abouty a uniform modification of the origf ina] elastic properties of the fabric, whereby the finished belt is properly conditioned,

not only 1to resist further stretching in use,

This invention relates to processes foi" v'Specification of Letters Patent. Patented June 13, 1922. 'Application filed September 4, 1918. Serial No. 252,634.

, than the other) and eliminating through the agency of my process the initial cause of the destruction of a treated belt.. l

A .further object of th'e. inventionis to provide a process for treating the materials for making up the belting to adapt the same but for the formation of al belt, which in for use therein, using cotton or other fabric in connection with pieces ofold wornr belts or leather to form a continuous, practical and durable belt -at a cost less than that of new leather belt, of the samesize and strength.

, Another object is to provide a process which will include the .preparation of the fabric under tension and also the preparationv of old leather to make these two materials serviceable for use in making of the compound beltiiig.

With these and other objects my invention consists in certain operations which are carried out upon suitable apparatus for making up the compound belting. One such set of appliances used for carrying out this ,process is illustrated in the accompanying drawings, which are hereinafter described,

the application of the process thereto is eX- plained and what I claim isset forth. l

A In the drawings. l i' Figure 1 is anelevation showing a mill room equipped with apparatus adapted to the purpose of. my process of. preparing the belting'parts and making of the Ibelting.

Figure 2 is a plan of the apparatus shown in Figure 1.

Figure 3 is a perspective view of the saturating tank of the apparatus.

Figure 4 is al sectional side elevation of part of said saturating tank.

Figure 5 is an' elevation of one of the roller suspension members `with roller attached',

Figure Gis a section view of a roller end showing the rod upon which' the roller is journaled with an elbow bracket attached. i

The figures in detail show two posts 1 and 2 between which the apparatus. is assembled on the floor 3. The apparatus vincludes la saturating tank 4, a pulley carriage 5, a fixed windlass 6, a press 7 and pulleys 8, 9 and 10 journaled in hangers, Fixed to walls, ad-

jacent they posts 1 and 2, as shown. The tank 4 is mounted upon rollers 4a, 4 and `has suspendedbeneath it a gas burner 11,

having a valve 12. Suitable flexible connections with a gas supply are provided, but not here shown which'permit of positioning the tank 4 in and out of use. Upon the ledge 4" of thetank 4 are fixed wringer blocks 13 and 14, in which is journaled the wringer roller 15. The block 13 is connected by the hinge 15I tothe upright guide 16, in which is `fitted, for reciprocation, the block 17. A screw crank 18, attachedto the block 17 and threaded in the guide '16, positions the block 17. To the block 14 is hooked the upright guide 19, in which is fitted, for reciprocation, the block 20. A screw crank 21, attached to the block 20 and threaded in the ide 19, ,positions the block 20. lJ ournaled 1n the blocks 17 and 20 is a roller 22,

' which is forced against the rollen 15 by means of the screw cranks 18 'and 21, when the hooks 23, 23,- on oppositesides of the upright 19, engage their pins '24, 24. Be@

neath the wringer, and releasably fixed by pins 25, 25, in the brackets v26, 26, is a scraper bar 27.

Mounted upon] the ledge 4", of the tank 4, are four bearings 28, 28 and 29, 29. In the bearings 28; 28 are journaled the stub shafts 30, 30 of the suspension members31, 31, each comprising a T-piece 32, to which is fixed a stub shaft 30. Also fixed to the T-piece 32 is cylindrical piece 33, upon which is journaled another T-pie'ce 34, held thereon by the cap 35. To the T-piece 34 isfixed the L-piece 36, positioned to have its end 37, bear upon the ledge 4b. Depending from and fixed to the T-piece 32 is a long piece 38, at the lower end of which is fixed a strap clamp 39, having also fixed therein the roller` bracket 40. Bolts 41, 41, 41 draw the clamp parts'together to grip the piece 38 and the bracket 40. In the brackets 40, 40 is'threaded'a rod 42, upon which is journaled a roller 43. A similar set of parts comprise the suspension members 44, 44, journaled on the bearings 29, 29, and supporting the roller 45. J ournaled in blocks 46, 46, fixed to the ledge 4b, is a roller 47, which completes the tank device, except for a pulley 48, fixed vt'o the shaft 49, of the wringer roller 15. The pulley 48 is connected by belt 50 to the pulle 51, fixed upon a line shaft 52, jour- --nale in the hanger 53, fixed to the beam 54. The-broken line 50a represents a crossed position of the belt 50. Adjoining the tank 4 is the pulley carriage 5, having a frame 54 mounted upon rollers 55, 55. The frame 5a has journaled upon it" two small pulleys 56 and 57 and one large pulley 58. To an extension 59, ofthe frame 5a., are fixed two cables 60, 60 attached and wound upon a shaft 61, journaled in the frame 62,of the windlass 6. Gearing 63 is attached to the shaft 61 and the shaft 64 of thecrank 65,

for winding the cables 60, 60. Twov rollers 1 66 and 67 are journaled upon the frame 62. Thev press 7h'as an open space in the standard'68 for the passage of the belt 69, which is shownpassingabove, between thel adjustable plate 70 and thetable 71. The hand wheel 72, with the usual threaded shaft 73, fixed thereto. l

-In operating the apparatus to carry out my process, one or more belts, such as 74, and 76 of the group 69, are passed over the pulleys and threadedthrough' the various devices as follows: starting at, say pul ley 10, the beltsy pass between the table 71 and the plate 70 of the press 7, thence over pulleys 67, 57 and around pulley 9. Returnmg itengages pulley 58 of the pulley carriage and passes back toward the column 1, around pulley 8 and over roller 47 passing down into the tank 4, under roller 43,

around roller 45, up over the ed es of the scraper bar 27, to between the wringer rollers 15 and 22. From there it passes over -pulleys 56 and 66 back to pulley 10, there being joints somewhere in-the belts, to make them continuous.

A solution of gelatinous substance with suitable ingredients, partially fills the tank 4 and through which the group of cotton belts is slowly passed to become thoroughly saturated.

The windlass 6 is operated to p-ull the cables 60, 60 and draw the pulley carriage 5 inra manner to have the pulley 58 tighten the belts. During tension on the belts,'the

rollers 43 and 45 are drawn -toward one another, but the suspension members .31 and- 44 lare prevented from turning in their respective bearings 28 and 29, by the L members `36, 36 bearing upon the tank ledge 4b.

"The course of the belt-s through the tank 4 is. shown in the Figure 3 by the dot and dash line S. The wringer is operated bypulley 48, turned by belt 50 from .the pulley 51 onY the driving shaft 52.- The scraper bar 27 1 rids the belts of part of excess solution and the remainder is squeezed out between the rollers 15 and` 32. .The tank solution is heated by the gas heater 11, if desired.

The belts are removed from the tank 4 by first unhooking the upper part 19 of the wrlnger and swinging the roller 22 up out .of the way. The pins 25, 25 are next withand tension is maintained thereby leather,

which has been previously cleansed and cut to desired thickness and width, is cementedv intermittently to vone surface of the belts and is fixed thereon in the press-7 and -held until the cement is set. Scarf joints are made between adjoining pieces of leather on the cotton so as to present an even surfaceI for Contact with pulleys in use. This process of vcovering -the belts with pieces of belts are covered on one side when they are cut through and removed from the apparatus and rolled up for delivery.

Cotton beltingcan be thus treated in this apparatus, omitting the leather coating and when` a suitable solution is used to saturate the cotton, the belt produced'will, be ready for use as a treated and properly stretched cotton belt, or if desired'an additional coating can be applied to one side, or both sides of the treated cotton belt to increase its frictional qualities.

.Belts produced by this process, and especially carried out on the said apparatus as above described and explained, are found t? run straight and give service equal to if not better than an all leather beltof the same strength.
